Gain-through-filtering enables tuneable frequency comb generation in passive optical resonators
摘要：
光学频率梳（OFC）由一组锁相等间隔的激光频率线组成，自Hänsch等人的开创性工作以来，已经使精密光谱学和计量学实现了巨大的飞跃。如今，OFC是从化学和生物学到天体物理学的大量进一步应用的基石，包括分子指纹和激光雷达等。驱动无源光谐振器是OFC产生的理想平台，具有紧凑性和低能量占用。我们在这里提出了一种新的技术，用于在外部驱动的光学谐振器的基础上的增益通过滤波过程，一个简单而优雅的方法，由于一个不对称的光谱滤波的泵浦波的一侧的重复频率可调的OFC的产生。我们展示了一个概念验证的实验结果，在光纤谐振器，开创了一种新的技术，不需要特定的工程谐振器色散产生频率捷变的OFC。
英文摘要：
Optical frequency combs (OFCs), consisting of a set of phase locked equally spaced laser frequency lines, have enabled a great leap in precision spectroscopy and metrology since seminal works of Hänsch et al. . Nowadays, OFCs are cornerstones of a wealth of further applications ranging from chemistry and biology to astrophysics and including molecular fingerprinting and LIDARs among others. Driven passive optical resonators constitute the ideal platform for OFCs generation in terms of compactness and low energy footprint. We propose here a new technique for generation of OFCs with tuneable repetition rate in externally driven optical resonators based on the gain-through-filtering process, a simple and elegant method, due to an asymmetric spectral filtering on one side of the pump wave. We demonstrate a proof-of-concept experimental result in a fibre resonator, pioneering a new technique that does not require specific engineering of the resonator dispersion to generate frequency agile OFCs.
